Hub size

What is the actual hub diameter on my ‘23 TB?

In looking at aftermarket wheels I see 106mm, 107mm, etc.
I thought I read the OEM hub is 78.1mm.
No one has an exact fit wheel?
If I want to install a larger tire I’ll need a shallower offset wheel.
With my OEM wheels and stock 275/60-20 Duelers I can barely get a finger between the UCA ball joint hub and the tire.

I bought Vision Brawl 20x10 -25 wheels and manufacturer states the hub size is 87.1, but I recall they came with a plastic hub insert adaptor that perfectly fit my 23 TB hub. Unsure if 87.1 is with or without the insert though.

A plastic shim? Seriously?

The wheels are lug centric. The centering ring just helps with ensuring they are centered while getting the lugnuts tight, which is why some are plastic. One set of rims I bought for my truck came with plastic hub rings. If you tighten them in stages by hand, there's really no need for a hub centric ring. 78.1mm is the correct hub diameter. I purchased a set of billet rings for a different set of wheels I have yet to put on my truck. The wheel hub diameter is 106mm, so 106mm OD to 78.1 ID. I test fit them just to ensure they would fit. I heard complaints with larger tires the hub ring is more important so I spent the $23 on the set from ebay because I'm going to be running 35" tires on 17x9 rims with -25mm offset.

Wish I had the internet when I built my first truck in 1981

100% true. I tried installing wheels without them initially, almost impossible to do without scratching paint.
